Protruding heel bones are mostly seen for three reasons. First, they are seen in traumatic heel fractures, and during the fracture recovery period, if there is a deformed healing fracture, it will lead to a protruding heel area. Second, seen in Achilles tendonitis, because the stopping point of the Achilles tendon, in the heel area, if there is an inflammatory reaction, it will lead to significant swelling in the heel area, which will see the protrusion of the heel area. Third, see in the heel bone degeneration, osteophytes, will also see the heel area with bone protrusion. And once the heel area bone protrudes, it is easy to cause the surrounding tissues to be irritated, thus causing pain and pressure pain in the heel area.
